Kigetsu belongs to the Shoshidai organization, tasked with managing cursed weaponry and overseeing the Chrysalids who wield these artifacts. He visibly reacts with surprise when witnessing Seiya Ichijo's emotional vulnerability concerning the tragic history of the Shiryu sword, indicating his understanding of the psychological burdens carried by those bonded to cursed weapons. His role within Shoshidai positions him as an observer of the organization's operations regarding cursed weapons and their wielders, though the available materials offer limited personal context regarding his history, motivations, or direct involvement in key events.
